Technical Description

1 System Overview

The Universal Motor Controller (UMC) is an intelligent motor controller for 3-phase AC induction motors
combining the two classical functions of motor protection and motor management in a single device plus
offering diagnostic and fieldbus communication. The device functions can be adjusted in a wide range to
cover the needs of different industries. UMC100 is a further development of the UMC22.

Function Overview

Protection Functions
• The UMC provides comprehensive motor protection including phase failure detection, adjustable motor
protection for stalled motors during startup or normal operation, configurable current limits to generate
trips or warnings and many more.
• Overload classes 5E, 10E, 20E, 30E and 40E
• Thermistor motor protection (PTC)
• Earth fault detection when used in IT networks
• Power and voltage based protection functions
• Supervision of the network quality (Total Harmonic Distortion)
• One device type covers the whole current range starting from 0.24 up to 63 A.
For higher currents up to 850 A additional current transformers are available.
Fieldbus Communication
• The UMC100 can be integrated into different fieldbus networks such as PROFIBUS DP , DeviceNet,
MODBUS and CANopen via the FieldBusPlug interface. All measured data, status signals and param-
eters can be accessed via fieldbus.
• It is also possible to use the UMC stand-alone (i.e. without FieldBusPlug).
• The motor protection and motor management is fully functional in the event of a bus failure.
• The fieldbus interface and the UMC can be separated. This offers many benefits in MCC applications
especially for withdrawable systems.
• Parameterisation of the protection and control functions can be carried out with the device description
files as defined by the different fieldbuses (e.g. GSD for PROFIBUS). In addition a Device Type Manager
(DTM) offering a very convenient device configuration via a laptop or within a control system is also
available.
Motor Management, Inputs and Outputs
• The UMC100-FBP provides six digital inputs, three relay outputs and one 24 V output. Therefore a wide
number of control functions can be covered from the base device.
• If further inputs or outputs are needed, the basic device can be expanded with an expansion module.
That provides an additional eight digital inputs, four relay outputs and an analogue output for driving an
analogue meter.
• Supported standard configurations are direct starter, reversing starter, star-delta starter, actuator, inching
mode and many more.
• The digital inputs can be configured in many ways to adapt the behaviour of the UMC100 to specific
user requirements.
• To execute customer specific applications the UMC100 allows free programming of its internal logic.
Function blocks for signal adjustment, boolean logic, timers, counters ... are available (see below).
• Different control stations (DCS, DI, Operation Panel ...) with individual, adjustable release opportunities
are available.
